Malahit DSP2 – Firmware – Changelog

Here you can find the changelog: Changelog (Перечень изменений) – Google Docs

Malahit DSP2 – Firmware Changelog – Test 2.10 2021.07.24

  • fixed battery voltage indication
  • fixed behavior of encoder buttons at low supply voltage
  • protection against false switching has been made – for switching on by three, set switch 2 to the On position.
  • added test function – increased display frequency. This reduces noise and increases the number of frames per second; To enable this function, set switch 3 to On. The function may not work correctly, if so, please let me know
  • the level of interference from the display is slightly reduced
  • changed the distribution of frequencies to which the input high-pass filters are turned on
  • when HiZ is turned on, the power supply of the external active antenna is automatically turned off;
  • added indication of external antenna power on – now the ANT indicator is highlighted in red if this function is enabled
  • the algorithm for displaying the picture on the display, slightly reduces the level of interference
  • changed the panorama display mode from “Pan & WTF Disabled / Enabled” to “Pan & WTF Single / Always”, while the panorama image is now always present, but it is updated once (when the settings are changed) or always.
  • fixed attenuators bugs

Malahit DSP2 – Firmware Changelog – Test 2.10 SAM 2021.07.31

  • SAM functionality

Malahit DSP2 – Firmware Changelog – Test 2.10 2021.08.13

  • corrected voltmeter operation
  • added SAMU, SAML modes
  • increased interface display frequency
  • improved switching between menus – now it does not pause
  • optimized the WFM algorithm, the receiver began to work faster
  • improvements made to Pan & WTF Single mode
  • removed graphical artifact near the SQL indicator

Malahit DSP2 – Firmware Changelog – Test 2.10 2021.08.16

  • improved suppression of interference from the display. Now in SSB, AM, NFM modes, noise reduction is automatically turned on. This slows down the speed of the user interface, but greatly reduces the clutter! This function is not used in WFM mode.

Malahit DSP2 – Firmware Changelog – Test 2.10 2021.08.17

  • Waterfall bandwith increased from 160khz to 192khz

Malahit DSP2 – Firmware Changelog – Test 2.10 2021.08.25

  • added Pseudo Stereo function. Added Pseudo Stereo button to Audio menu
  • added the ability to switch audio output in the HARD menu – added the Audio out button. Ph + Sp – headphones and speaker, Phone – headphones, Speaker – speaker
  • added PGA BST function to HARD menu. This function can be useful when receiving strong signals and receiving congestion. When overloading, you must select the Disabled position.
  • changed the arrangement in the frequency bar under the spectrum
  • changed the behavior of the receiver with a short press on the power button. Now, with a short press in the receiver, the touchscreen is turned off, the spectrum and waterfall work similarly to the Pan & WTF Single option.
  • the lower operating frequency has been reduced from 50 kHz to 20 kHz.

Malahit DSP2 – Firmware Changelog – 2.10D 2021.08.26

Alle changes between 2.0 and all test version to 2.10D are included:

  • fixed battery voltage indication
  • fixed behavior of encoder buttons at low supply voltage
  • protection against false switching has been made – for switching on by three, set switch 2 to the On position.
  • added test function – increased display frequency. This reduces noise and increases the number of frames per second; To enable this function, set switch 3 to On. The function may not work correctly, if so, please let me know

  • increased interface display frequency
  • improved switching between menus – now it does not pause
  • optimized the WFM algorithm, the receiver began to work faster
  • improvements made to Pan & WTF Single mode
  • removed graphical artifact near the SQL indicator
  • correction of S meter was introduced depending on the range. Now the S meter is accurate enough
  • improved suppression of interference from the display. Now in SSB, AM, NFM modes, noise reduction is automatically turned on. This slows down the speed of the user interface, but greatly reduces the clutter! This function is not used in WFM mode.
  • added Pseudo Stereo function. Added Pseudo Stereo button to Audio menu
  • added the ability to switch audio output in the HARD menu – added the Audio out button. Ph + Sp – headphones and speaker, Phone – headphones, Speaker – speaker
  • added PGA BST function to HARD menu. This function can be useful when receiving strong signals and receiving congestion. When overloading, you must select the Disabled position.
  • changed the arrangement in the frequency bar under the spectrum
  • the lower operating frequency has been reduced from 50 kHz to 10 kHz.
  • span increased to 192 kHz.
  • changed properties of USB audio devices – now IQ 192kHz, simple audio – 48kHz.

Malahit DSP2 – Firmware Changelog – Test 2.10E 2021.10.08

  • Fixed the scale with the image often – the scale is made in the color of the panorama, added horizontal lines
  • Improved retro-scale – brought to v1.10C
  • EMI reductuin function added: decreased noise by changing display frequency
  • fixed moving from AUDIO menu to other menus – now without delay
  • Gradual volume increase on power on
  • Improved dead band 380-403,3MHz
  • Changes The encoders work differently – now you can use the audio encoder independently. The settings are changed with the frequency encoder
  • Sleep time option was removed from Visual menu
  • added color scheme for waterfall – now there are three modes of work – classic, black-white and white-black

Malahit DSP2 – Firmware 2.10D – New options

You can activate two experimantal fuctions, which less interferences fro the TFT, more FPS on the screen and a new power on mode.

  • Switch 2: The receiver power on with 3 pushes on the power button (for me it takes 5 pushes), without only one push is needed
  • Switch 3: Added in test firmware from 2021.07.24, but don´t need to be activated in the last firmware from 2021.08.16, because it´s default activated

Malahit DSP2 – Firmware update

At first: You can´t do any permanent damage to the Malahit DSP2. If the firmware updates fails, the Malahit DSP2 remains in the DFU mode an can be flashed again.

Malahit DSP2 – Firmware Download

I have received permission from Georgiy to upload the firmware to my server. You can download it here:

You can found the chagelog on the bottom of this page.

Malahit DSP2 – Firmware Update – DFU mode

At first you must start the Malahit DSP2 in DFU Mode:

  1. Push the two encoder buttons at the same time and hold until step 4.
  2. Push the power button
  3. Release the two encoder buttons
  4. Release the power button
  5. If the LED of the Malahit DSP is blinking green and red, it is in DFU mode

If it don´t work, do it faster. If it is to slow, it don´t work.

Now the Malahit DSP2 should be in the DFU mode. You can plug in the USB cable to Malahit DSP2 and computer. If you open the device manager in Windows 10, you should see this:

Please note: You need a USB cable with data cables. A USB cable only for charging isn´t working.

Malahit DSP2 – Firmware Update – STM32CubeProgrammer

Now you must start the tool STM32CubeProgrammer. If you don´t have installed it, you can find it here:

Malahit DSP2 – Firmware Update – STM32CubeProgrammer – Windows 11

I tried to start the STM32CubeProgrammer x64 in Windows 11 and i got this error:

You have to start the STM32CubeProgrammer on Windows 11 as Admin, than it´s starts without error:

Malahit DSP2 – Firmware Update – STM32CubeProgrammer – Connect Malahit DSP2

In the STM32CubeProgrammer you have to set the dropdown list to USB. Than you have to click on the refresh button right from the “Port USB1

Than you have to click on the button “Connect“:

Now it should look like this:

Malahit DSP2 -Firmware Update – STM32CubeProgrammer – Flash firmware

Now you have to click on the “Erasing and Programming” button:

Now you can select the firmware file do you want to upgrade (you find all possible versions on the top of the page, extract the downloaded file first) and select the checkboxes “Verfify programming” and “Run after programming“. The firmware file can be a hex or a bin file, both file types are working.

At the end you must press the button “Start Programming“.

If you get this error, try to flash the same firmware file a second time. Perhaps you have to reconect the Malahit DSP2 to the computer to do it. Keep calm, the device remains in the DFU mode.
